Electrowetting display apparatus and method of manufacturing the same

An electrowetting display apparatus comprising:

• a first substrate that includes at least one pixel area, the first substrate including a first electrode disposed in the pixel area and receiving a gray-scale voltage and a second electrode insulated from the first electrode and receiving a reference voltage;
• a second substrate that faces the first substrate;
• a black fluid layer disposed between the first substrate and the second substrate in the pixel area, the black fluid layer moving due to a voltage difference between the gray-scale voltage and the reference voltage;
• and
• a color filter disposed on a surface of the second substrate that is adjacent to the black fluid layer, wherein the color filter has a first thickness in an area corresponding to the first electrode and a second thickness in an area corresponding to the second electrode, and the first thickness is larger than the second thickness.
